The organization does not want to retrain the foundation model every time a document changes.Which TWO approaches are most appropriate?A. Use Retrieval Augmented Generation (RAG) to retrieve relevant documents at inference time.B. Store document embeddings in a suitable vector database for similarity search.C. Fine-tune the foundation model every time a document changes.D. Increase the model's temperature.E. Remove the company's documents from the AI workflow.Correct Answers: A and BExplanation:RAG allows the application to retrieve relevant information from an external knowledge source at inference time without retraining the foundation model for every document update. A vector database can store embeddings and support efficient similarity-based retrieval.Question 2 — AWS GovernanceA security team wants to determine which user or AWS service made a specific API call that modified resources in its AWS environment.Which AWS service should the team use?A. AWS CloudTrailB. AWS ConfigC. AWS ArtifactD. AWS Audit ManagerCorrect Answer: AExplanation:AWS CloudTrail records AWS API activity and can help organizations determine who or what performed an action, what action was performed, and when it occurred.Question 3 — Responsible AIA company discovers that its AI model performs significantly better for one demographic group than another. The organization wants to investigate and address the issue before deploying the model.What is the MOST relevant concern?A. Bias and fairnessB. Model temperatureC. TokenizationD. Inference batch sizeCorrect Answer: AExplanation:Differences in model performance across demographic groups can indicate bias and fairness concerns. Organizations should evaluate model behavior across relevant groups and take appropriate steps to identify and mitigate unfair outcomes.Question 4 — SecurityAn enterprise AI assistant can access internal documents and execute actions through connected business tools. The security team wants to limit the potential impact if a malicious prompt attempts to manipulate the assistant.Which TWO practices are most appropriate?A. Apply least-privilege permissions to the AI application's data and tools.B. Monitor and validate inputs and outputs for suspicious or unauthorized behavior.C. Give the AI administrator access to every enterprise system.D. Disable authentication for connected tools.E. Allow the assistant to access all company data by default.Correct Answers: A and BExplanation:Least-privilege access limits what the AI system can access or execute. Monitoring and validation provide an additional security layer for detecting suspicious behavior. Together, these controls help reduce the potential impact of prompt injection and other adversarial threats.Question 5 — Model SelectionA company needs to deploy a foundation model for a high-volume customer-facing application. The application requires fast responses and has a strict inference budget.Which factor should be prioritized when selecting the model?A. Cost and latency requirementsB. Maximum possible model sizeC. Number of training parameters aloneD. Highest temperature settingCorrect Answer: AExplanation:Model selection should consider the requirements of the specific workload. For a high-volume, latency-sensitive application with a strict budget, inference cost and response latency are important selection criteria alongside performance and capability.Question 6 — Data GovernanceA company has multiple datasets with different business and regulatory requirements. Some data must be retained for several years, while other information should be deleted after a short period.What is the BEST approach?A. Define data retention and lifecycle policies based on data type, business requirements, and applicable regulations.B. Retain all data indefinitely.C. Use the same retention period for every dataset.D. Allow individual employees to decide how long data should be retained.Correct Answer: AExplanation:Effective data governance requires defined retention and lifecycle policies that reflect the nature of the data, business requirements, and applicable regulatory obligations. This helps organizations control data throughout its lifecycle and avoid unnecessary retention.Is this practice-test course for you?This course is ideal if you:Are preparing for the AWS Certified AI Practitioner (AIF-C01) exam.Want to test your knowledge before scheduling the certification exam.Prefer scenario-based practice rather than only reading theory.Want to identify the topics where you need additional preparation.Want to practice both single-answer and multiple-answer questions.Are looking for a structured way to measure your readiness across the major AI and AWS topics.Take the 6 practice tests, review the explanations, identify your weak areas, and build your confidence for the AWS Certified AI Practitioner (AIF-C01) exam.
